  iommu/sva: Restore SVA handle sharing (2024-02-23 16:45:05 +0100)

----------------------------------------------------------------
IOMMU Fixes for Linux v6.8-rc5

Including:

	- Intel VT-d fixes for nested domain handling:
	  - Cache invalidation for changes in a parent domain
	  - Dirty tracking setting for parent and nested domains
	  - Fix a constant-out-of-range warning

	- ARM SMMU fixes:
	  - Fix CD allocation from atomic context when using SVA with SMMUv3
	  - Revert the conversion of SMMUv2 to domain_alloc_paging(), as it
	    breaks the boot for Qualcomm MSM8996 devices

	- Restore SVA handle sharing in core code as it turned out there are
	  still drivers relying on it
